Definitions

  • the present invention relates to a linear compressor, in particular for use for compressing refrigerant in a refrigerator, and in particular a drive unit for driving an oscillating piston movement for such a linear compressor, see U55779455 with the closest prior art.
  • the drive unit comprises a frame and a mounted in the frame via a diaphragm spring vibrating body.
  • the oscillating body comprises a permanent magnet, a piston rod rigidly connected to the permanent magnet, and a piston articulated to the piston rod and reciprocable in a cylinder.
  • the movement of the piston is driven by an electromagnet arranged around the cylinder, which interacts with the permanent magnet.
  • a disc-shaped diaphragm spring is bolted to the center of the piston rod, and the outer edge of the diaphragm spring is connected to a yoke which surrounds the cylinder, the electromagnet and the permanent magnet.
  • the oscillating body and the diaphragm spring form a vibratory system whose natural frequency is determined by the mass of the oscillating body and the diaphragm spring and the stiffness of the diaphragm spring.
  • the diaphragm spring allows only small vibration amplitudes, since each deflection of the vibrating body is associated with an expansion of the diaphragm spring. Due to the low vibration amplitude, it is difficult to reliably make the dead volume of the cylinder small. However, the larger the dead volume, the worse the efficiency of the compressor. The small stroke also forces the cylinder to be proportionate to the large diameter length to achieve a given throughput. It is complicated to adequately seal the correspondingly large circumference of the piston.
  • a gas pressure bearing for the piston is provided, that is, the swept by the piston cylinder wall has openings that communicate with the high pressure outlet of the Linear compressor are connected to form a gas cushion between the inner wall of the cylinder and the piston.
  • a compressed gas bearing only works if the required overpressure is present at the outlet of the linear compressor, that is not when the compressor starts or runs out. At these times, there is a risk that the piston grinds on the cylinder wall, so that the compressor wears prematurely.
  • a linear compressor according to the preamble of claim 2 is made US 6 641 377 B2 known.
  • each piston is held by two respective two-armed diaphragm springs.
  • the arms Due to the curvature of the arms, an enlarged piston stroke is possible.
  • the arms are easier to deform in the longitudinal direction of the piston than transversely thereto, so that they counteract contact of the piston with the cylinder wall.
  • the oscillation frequency of the piston In order to achieve a desired throughput of the compressor, the oscillation frequency of the piston must not be too low. This oscillation frequency is higher, the stiffer the diaphragm spring is. However, too stiff a diaphragm spring runs the risk of becoming tired at high vibration amplitudes.
  • Object of the present invention is to provide a drive unit for a linear compressor with a frame and mounted in the frame via a diaphragm spring vibrating body in which the diaphragm spring without risk of fatigue allows a large stroke of the vibrating body, so that a high throughput at low piston diameter can be achieved.
  • the arms of the at least one diaphragm spring should be made of a very thin material. Its strength can be so tight that it is only sufficient to prevent lateral deflection of the oscillating body. However, such a weak diaphragm spring would lead to a low natural frequency of the drive unit and thus at a given stroke to a low throughput of a driven by the drive unit compressor.
  • each arm is associated with a return spring, which counteracts a deformation of the arm, so that the diaphragm spring forms together with the return springs in each case an elastic system whose rigidity is significantly greater than that of the diaphragm spring alone.
  • each arm has a single unidirectional curved section.
  • Such an arm also exerts a torque on the oscillating body carried by it during deflection, so that, together with the reciprocating movement, a torsional vibration of the oscillating body is also excited.
  • a rotationally symmetrical design of at least parts of the compressor may be required.
  • each arm has two portions curved in different directions. Again, since the different curved portions cause torques in opposite directions, so that the torque of each arm can be made very small or made to disappear.
  • the oscillating body is reliably guided linearly in the direction of the desired oscillatory movement, and a lateral evasive movement, which could lead to contact between a piston carried by the oscillating body and a cylinder surrounding the piston, can be avoided.
  • the arms of a same diaphragm spring preferably hang at their attacking ends on the frame and / or at their attacking on the vibrating body ends respectively in one piece together.
  • the frame engaging ends may be connected by a frame integral with the leaf springs.
  • the effective spring constant of the combination of diaphragm spring and return spring can be made adjustable in order to tune the natural frequency of the drive unit as needed.
  • a coil spring is preferably used.
  • the invention also relates to a linear compressor having a working chamber, a reciprocating in the working chamber for compressing a working fluid piston and a coupled to drive the reciprocating motion to the piston drive unit of the type described above.
  • Fig. 1 shows a partially sectioned side view of a linear compressor.
  • the compressor has a frame with a central chamber 21, wherein in two opposite walls, here with reference to the illustration in FIG. For the sake of clarity, referred to as ceiling 22 and bottom 23, openings are formed, through which play a rod-shaped oscillating mass 24 extends.
  • the chamber 21 is provided to receive unillustrated electromagnets for driving a reciprocating motion of a permanent magnet inserted into the oscillating mass 24.
  • the ends of the oscillating mass 24 are fastened to central regions 16 of two diaphragm springs 8 by means of screws or rivets 25.
  • the diaphragm spring 8 has a closed outer ring or frame 13 of rectangular shape, which stabilizes it prior to installation in the compressor and protects against bending. From the corners of the frame 13, four arms 14 extend toward the central region 16, each of which is composed of three straight sections 17 and two curved sections 18, 19 connecting the sections 17. The two sections 18, 19 of each arm 14 each have opposite direction of curvature. Four holes 20 for attachment of the diaphragm spring 8 are located at the corners of the frame thirteenth
  • each diaphragm spring 8 rests on projecting from the ceiling 22 and the bottom 23 of the central chamber 21 webs 26.
  • the diaphragm springs 8 are held on the webs 26 respectively by screws or rivets 27, each having a foot 28 of an upper or lower yoke 29, 30 and one of the holes 20 in the corners of the frame 13 intersect and engage in the central chamber 21.
  • the height of the webs 26 determines the maximum stroke of the movement of the oscillating mass 24; If this maximum stroke is exceeded, the central regions 16 of the diaphragm spring 8 abut against the ceiling 22 or floor 23.
  • the lower yoke 30 carries two coil springs 31, which are each placed so that free headers 32 of them, as well as a dash-dotted outline in Fig. 2 indicated, each touching the curved portions 18 of two arms 14, if this after deflected down, and thus resist a deflection of the oscillating mass 24 down.
  • Corresponding coil springs 31, which contact the curved portions 18 of arms of the upper diaphragm spring 8 and counteract upward deflection of the oscillating mass, are provided on the upper yoke 29.
  • the upper yoke 29 also carries a cylinder 33 into which a piston connected to the oscillating mass 24 via a piston rod 10, which is not visible in the figure, can be moved back and forth. Since the oscillating mass 24 is guided exactly linearly by the two diaphragm springs 8, the piston rod 12 and with it the piston carried by it can not move transversely to the direction of movement, and grinding of the piston on the inner wall of the cylinder 33 can be avoided. As a result of the movement of the piston, fluid is sucked in via a suction port 34 of the cylinder 33, compressed and expelled again via a pressure port 35.
  • the oscillating mass 24 When the oscillating mass 24 is at one of the reversal points of its trajectory, all of its kinetic energy is stored in the form of strain energy in the diaphragm springs 8 and the coil springs 31, the distribution of energy being directed to the types of springs according to their respective spring constants.
  • the diaphragm springs can therefore be made very thin and easily deformable, so that no material fatigue occurs even with long-term operation, because the energy that can not store the diaphragm springs for lack of sufficient rigidity, can be absorbed by appropriately sized coil springs 31.
  • diaphragm spring compressors with different throughput can be realized by the diaphragm springs are each combined with coil springs with different spring constants, each resulting in different natural frequencies of the oscillatory system.
  • Fig. 3 shows a modification of the diaphragm spring 8 Fig. 3 , which can be used in their place in the compressor of Fig. 4.
  • the protective outer frame 13 has been eliminated; Instead, only the two right and the two left arms 14 are connected at their ends remote from the central region 16 by a strip of material 34.
  • the arms are here at the same outer dimensions of the diaphragm spring wider and thus stiffer than that of the spring Fig. 2 , The operation does not differ from that of the diaphragm spring Fig. 3 ,
